Copper is usually mined in two ways: open-pit mining and underground mining. Open-pit mining is used for copper deposits closer to the surface. Enormous machines dig up the ground in stair-stepped layers (called …

Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leachingis the process of using percolating …
